You have to write your own one. The Bison manual has a simplistic example implementation for you. A .y source with its own yyerror() definition will work in both Yacc and Bison, so this difference in behaviour shouldn't cause much harm. -- Hans-Bernhard Broeker (broeker AT physik DOT rwth-aachen DOT de) Even if all the snow were burnt, ashes would remain.
